                            CERTIFICATE OF AMENDMENT

                                       OF

                          CERTIFICATE OF INCORPORATION

                                       OF

                                  HOWTEK, INC.

            THE UNDERSIGNED, being a duly authorized officer of Howtek, Inc., a
corporation existing under the laws of the State of Delaware (the
"Corporation"), does hereby certify as follows:

            1. That the Certificate of Incorporation of the Corporation has been
amended as follows by striking out Article FIRST as it now exists and inserting
in lieu and instead thereof a new Article FIRST reading as follows:

            "FIRST: The name of the Corporation is:

            icad, inc."

            2. That the Certificate of Incorporation of the Corporation has been
further amended as follows by inserting a new Article TENTH reading as follows:

            "TENTH: 1. Indemnification.

            The Corporation shall, and does hereby, indemnify to the fullest
extent permitted or authorized by the Delaware General Corporation Law or
judicial or administrative decisions, as the same exists or may hereafter be
amended or interpreted differently in the future (but, in the case of any such
amendment or interpretation, only to the extent that such amendment or
interpretation permits the Corporation to provide broader indemnification rights
than permitted prior thereto), each person (including the current and future
heirs, beneficiaries, personal representatives and estate of such person) who
was or is a party, or is threatened to be made a party, or was or is a witness,
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (a "Proceeding") and whether
the basis of such Proceeding is an allegation of an action in an official
capacity of such person related to the Corporation or any other capacity while
such person is serving as an officer, director, employee or agent of the
Corporation, against any liability (which for purposes of this Article shall
include any judgment, settlement, penalty or fine) or cost, charge or expense
(including attorneys' fees) asserted against him or incurred by him by reason of
the fact that such indemnified person (1) is or was a director, officer or
employee of the



Corporation or (2) is or was an agent of the Corporation as to whom the
Corporation, by action of its Board of Directors, has agreed to grant such
indemnity or (3) is or was serving, at the request of the Corporation, as a
director, officer or employee of another corporation, partnership, joint
venture, trust or other enterprise (including serving as a fiduciary of any
employee benefit plan) or (4) is or was serving as an agent of such other
corporation, partnership, joint venture, trust or other enterprise described in
clause (3) hereof as to whom the Corporation, by action of its Board of
Directors, has agreed to grant such indemnity. Each director, officer, employee
or agent of the Corporation to whom indemnification rights under this Section 1
of this Article have been granted shall be referred to as an "Indemnified
Person."

            Notwithstanding the foregoing, except as specified in Section 3 of
this Article, the Corporation shall not be required to indemnify an Indemnified
Person in connection with a Proceeding (or any part thereof) initiated by such
Indemnified Person, unless such authorization for such Proceeding (or any part
thereof) was not denied by the Board of Directors of the Corporation prior to
sixty (60) days after receipt of notice thereof from such Indemnified Person
stating his intent to initiate such Proceeding and any such indemnification
shall be made only upon such terms and conditions as the Board of Directors may
deem appropriate.

            2. Advance of Costs, Charges and Expenses.

            Costs, charges and expenses (including attorneys' fees) incurred by
an officer, director, employee or agent who is an Indemnified Person in
defending a Proceeding shall be paid by the Corporation to the fullest extent
permitted or authorized by the Delaware General Corporation Law or judicial or
administrative decisions, as the same exists or may hereafter be amended or
interpreted differently in the future (but, in the case of any such future
amendment or interpretation, only to the extent that such amendment or
interpretation permits the Corporation to provide broader rights to advance
costs, charges and expenses than permitted prior thereto), in advance of the
final disposition of such Proceeding, upon receipt of an undertaking by or on
behalf of the Indemnified Person to repay all amounts so advanced in the event
that it shall ultimately be determined by final judicial decision that such
person is not entitled to be indemnified by the Corporation as authorized in
this Article and upon such other terms and conditions, in the case of an agent
as to whom the Corporation has agreed to grant such indemnity, as the Board of
Directors may deem appropriate. The Corporation may, upon approval of the
Indemnified Person, authorize the Corporation's counsel to represent such person
in any Proceeding, whether or not the Corporation is a party to such



Proceeding. Such authorization may be made by the Board of Directors by majority
vote, including directors who are parties to such Proceeding.

            3. Procedure for Indemnification.

            Any indemnification or advance under this Article shall be made
promptly and in any event within sixty (60) days upon the written request of the
Indemnified Person (except in the case of a claim for an advancement of costs,
charges or expenses, in which case the applicable period shall be twenty (20)
days). The right to indemnification or advances as granted by this Article shall
be enforceable by the Indemnified Person in any court of competent jurisdiction
if the Corporation denies such request under this Article, in whole or in part,
or if no disposition thereof is made within sixty (60) days or twenty (20) days,
as may be applicable. Such Indemnified Person's costs and expenses incurred in
connection with successfully establishing his right to indemnification or
advancement of costs, charges or expenses, in whole or in part, in any such
action shall also be indemnified by the Corporation. It shall be a defense to
any such action that the claimant has not met the standard of conduct, if any,
required by the Delaware General Corporation Law or judicial or administrative
decisions, as the same exists or may hereafter be amended or interpreted
differently in the future (but, in the case of any such future amendment or
interpretation, only to the extent that such amendment or interpretation does
not impose a more stringent standard of conduct than permitted prior thereto),
but the burden of proving such defense shall be on the Corporation. Neither the
failure of the Corporation (including its Board of Directors or any committee
thereof, its independent legal counsel, and its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant or advancement for the claimant is proper in the circumstances
because he has met the applicable standard of conduct, if any, nor the fact that
there has been an actual determination by the Corporation (including its Board
of Directors or any committee thereof, its independent legal counsel, or its
stockholders) that the claimant has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that the claimant has
not met the applicable standard of conduct.



            4. Non-Exclusivity; Survival of Indemnification.

            The indemnification and advancement provided by this Article shall
not be deemed exclusive of any other rights to which those Indemnified Persons
may be entitled under any agreement, vote of stockholders or disinterested
directors or recommendation of counsel or otherwise, both as to actions in such
person's official capacity and as to actions in any other capacity while holding
such office or position, and shall continue as to an Indemnified Person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of the heirs, beneficiaries, personal representatives and the estate of
such person. All rights to indemnification and advancement under this Article
shall be deemed to be a contract between the Corporation and each Indemnified
Person who serves or served in such capacity at any time while this Article is
in effect. Any repeal or modification of this Article or any repeal or
modification of relevant provisions of the Delaware General Corporation Law or
any other applicable laws shall not in any way diminish any rights to
indemnification of such Indemnified Person, or the obligations of the
Corporation arising hereunder, for claims relating to matters occurring prior to
such repeal or modification.

            5. Savings Clause.

            If this Article or any portion hereof shall be invalidated on any
ground by any court of competent jurisdiction, then the Corporation shall
nevertheless indemnify and advance costs to each Indemnified Person as to costs,
charges and expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement with respect to any Proceeding, including an action by or in
the right of the Corporation, to the full extent permitted by any applicable
portion of this Article that shall not have been invalidated and as permitted by
the Delaware General Corporation Law."

            3. That the Certificate of Incorporation of the Corporation has been
further amended as follows by inserting a new Article ELEVENTH reading as
follows:

            "ELEVENTH: 1. The number of directors comprising the Board of
Directors shall be such number as may be from time to time fixed by resolution
of the Board of Directors. The directors shall be classified in respect to the
time for which they shall severally hold office, by dividing them into three
classes. The number of directors in each class shall be as nearly equal as
possible. At each annual election, any vacancy in any class may be filled and
the successors to the directors of the class whose terms shall expire in that
year shall be



elected to hold office for the term of three years, and the term of office of
one class of directors shall expire in each year. In the event the number of
directors is increased, election may be made to a class of directors with terms
expiring in three years or less in order to maintain proportionate equality
between the classes.

            2. The directors shall be elected by the holders of shares of stock
of the Corporation entitled to vote on the election of directors, and directors
shall be elected by a plurality vote. The directors shall be divided into three
classes, designated as Class I, Class II and Class III as set forth in Section 1
of this Article ELEVENTH. The Class I directors shall serve until the annual
meeting of stockholders held in 2003, the Class II directors until the annual
meeting of stockholders held in 2004, and the Class III directors until the
annual meeting of stockholders held in 2005 and, in each case, until their
successor(s) are duly elected and qualified. At each annual meeting of
stockholders commencing with the annual meeting to be held during the calendar
year 2003 each of the successors to the Directors of the Class whose term shall
have expired that year shall be elected for a three-year term. If the number of
directors is changed, any increase or decrease shall be apportioned among the
classes so as to maintain the number of directors in each class as nearly equal
as possible, and any additional director of any class elected to fill a vacancy
resulting from an increase in such class shall hold office for a term that shall
coincide with the remaining term of that class, but in no case will a decrease
in the number of directors shorten the term of any incumbent director. A
director shall hold office until the annual meeting for the year in which his
term expires and until the successor shall be elected and shall qualify,
subject, however to prior death, resignation, retirement, disqualification or
removal from office. Any vacancy occurring in the Board of Directors, including
any vacancy created by reason of an increase in the number of directors, shall
be filled for the unexpired term by the concurring vote of a majority of the
directors then in office, whether or not a quorum, and any director so chosen
shall hold office for the remainder of the full term of the class of directors
in which the new directorship was created or the vacancy occurred and until such
director's successor shall have been elected and qualified.
